I have no more information other than what my source told me.
As for Nate's speed, what I can say is this after watching him run the 100 seven or so times his senior year and watching him play at least five games in the run up to the state championship game: Nate was finisher in track. He reveled in his slow start (he didn't have the best start out of the block his coach said) and then dusting people in the last 50 meters or so.
As a receiver you never saw the slow speed. What you did see was the occasional inconsistency. We shall see. He has to get in school and show that he can handle it in the classroom first.
